Possible SOAP version mismatch

Nov 04, 2008 09:32 PM|LINK

I added a web service into an ASP web application,

after I ran the application and called the web service,

the web page showed following message:

Possible SOAP version mismatch: Envelope namespace http://schemas.xmlsoap.org/disco/ was unexpected. Expecting http://schemas.xmlsoap.org/soap/envelope/.

---------------------------------------------------------------------------

I do not understand what is the problem.

Thanks everyone who tries to help me.

Check that the URL the client sends messages to is correct.

Also use a tool like Fiddler to capture the messages that are sent and received and publish them here.

I found there is different thing from regular consuming web service,

the url of adding web service which I wanna add is https://xxxxxxxxxx/xxx/soap.php?wsdl , it is a php file

in the text book, regular url of adding web reference is http://xxxx/xxxx/something.asmx , it is web service file

Would this be the problem?

however, when I added https://xxxxxxxxxx/xxx/soap.php?wsdl this php file, I also can see how many methods appear on

add web reference page

the ?WSDL is to see the WSDL, but it is not to consume the service.
Use the url without this extension.
Publish the SOAP you traced with fiddler here.

Thank you for your patient.

I re-add the web reference and also took off "?wsdl", but I still get the same massege after I called the web service.

Following is the information from Fiddler:

I re-add the web reference, and took off "?wsdl", but I still got the same information after I called that web service.

There is information from Fiddler:

Can you share also the response? mainly I want to know if the server throws this exception or the client when handling the server response.

Additionaly if you can share the WSDL we can see what soap versions are expected and what url is specified inside it.

Also - do you have any working client at all to this service? even a php one. We could compare what the working and non-working clients send.

Yes, the error message is from my code:

catch(System.Web.Services.Protocols.SoapException ex) {

Response.Write(ex.Message.ToString());

}

and this code return the message:

Possible SOAP version mismatch: Envelope namespace http://schemas.xmlsoap.org/disco/ was unexpected. Expecting http://schemas.xmlsoap.org/soap/envelope/.

Otherwise, the WSDL is :

<?xml version="1.0" encoding="utf-8"?>

<xsd:complexType name="HeaderStruct">

=============================================

I saw other web site says if the envelope namespace url is "http://schemas.xmlsoap.org/soap/envelope/", the wsdl should be SOAP version 1.1,

and this url is match the error message "Expecting http://schemas.xmlsoap.org/soap/envelope/"

So I guess the wsdl is SOAP 1.1 , however, I don't know how can I fix it.

Moreover, in the caching section of Fiddler, it says:

Response headers do not contain caching-related directives.

Thank you so much.

Please publish the response that comes back from the server (using fiddler).

If what you published above is the response then the server url returns a WSDL file instead of a SOAP envelope. One reason may be that you are using a wrong url for the run time.

If you will publish the full WSDL I can see what url appears inside it.

Also check if there is any working client at all for this service (even a php one) so we can see what is the difference between what it sends and what you send.
